In the LIA’s court filings, seen by Reuters, the LIA said an appeal would be confined to the LIA’s claim in respect of four trades made in April, and a prestigious internship that Goldman Sachs offered to Haitem Zarti, the younger brother of Mustafa Zarti, a key LIA decision-maker at the time.

The Libyan Investment Authority sued Goldman in 2014 claiming the bank “took unfair advantage” of the country’s unsophisticated bankers and persuaded them to buy complex derivative instruments that by 2011 ended up being worthless.

The LIA was set up in 2006 after economic sanctions on the country were lifted.

A Goldman banker, Youssef Kabbaj, was singled out in the suit for orchestrating gifts and favors, including a prostitute, that ultimately won the bank LIA’s business.

Kabbaj also arranged the internship for Haitem Zarti, the suit said.

While LIA lost $1.2 billion on the risky trades, Goldman earned $367.7 million profit, lawyers for the LIA claimed in court papers.

Goldman denied it did anything improper.

LIA’s claims are “both unusual and ambitious,” the bank’s lawyers said in court papers at the time.

LIA lost money because global markets turned down for longer than expected, Goldman said in the court papers.

In addition, “Goldman Sachs or myself never paid for any LIA employee any improper entertainment,” Kabbaj told Bloomberg before the court decision. “I am under a strong confidentiality agreement but I expect Goldman Sachs to correct the facts and protect my reputation.”
